What is the recommended minimum contrast ratio for large text?

• A. 1:1
• B. 2:1
• C. 3:1
• D. 4.5:1

Answer: (C)

The recommended minimum contrast ratio for large text is 3:1. This standard is established to ensure that text is easily readable for individuals with visual impairments, particularly those with low vision or color blindness. Large text, defined as being 18-point (or 14-point bold) and above, does not require as high a contrast ratio as smaller text because it is generally easier to see. The rationale behind the 3:1 ratio is that higher contrast makes text more legible against its background, which is crucial for accessibility. This threshold helps ensure that users with varying levels of visual perception can read content without straining their eyes, thus enhancing their overall user experience on websites or digital platforms. Maintaining this ratio is part of creating accessible web content that complies with guidelines like the Web Content Accessibility Guidelines (WCAG).
